Worm castings, also known as vermicompost or vermicastings, are created when organic matter passes through the digestive system of earthworms. The earthworm’s special digestive process transforms organic material into a fantastic soil supplement that plants simply love. Combine G&B ORGANICS WORM-GRO with your native soil or use it as an effective “worm tea” to fertilize a variety of plants, flowers, vegetables and even lawns. By mixing WORM-GO into your soil at the drip line, you’ll be helping your plants resist disease and pests while increasing beneficial microbe activity that creates a great soil environment in-ground or in-containers.
